Put flours in bowl and whisk to combine. Whisk eggs, water and oil in bowl, combine with dry mixture. Add pinch of salt and combine, then knead dough until smooth, about 15 minutes. Wrap in plastic wrap and let it cool in fridge for 1 hour while you make filling.
Mixing all of the above in a kitchen mixer is a whole lot easier than doing it by hand and takes a lot less time.
